I have one of the old Fiskars grey rotary cutter with the orange release button, I like it and it works for me. The newest Fiskars cutter is much more difficult to open and close, the design has been changed. If you've got arthritic fingers/thumbs,
this isn't the cutter for you. I still like the ergonomic Olfa cutters the best. I prefer the 45mm for most cutting jobs, but for multiple layers, the 60mm is a better choice.
